[PATCH v2] serial: liteuart: fix missing drvdata

From: Ilia Sergachev <hidden>
Date: 2021-11-15 10:10:48
Subsystem: litex platform, the rest, tty layer and serial drivers · Maintainers: Karol Gugala, Mateusz Holenko, Joel Stanley, Linus Torvalds, Greg Kroah-Hartman, Jiri Slaby

drvdata has to be set in _probe() - otherwise platform_get_drvdata()
causes null pointer dereference BUG in _remove()

Fixes: 1da81e5562fa ("drivers/tty/serial: add LiteUART driver")
Signed-off-by: Ilia Sergachev <redacted>
